Are we sure about Conky being accurate? I still notice that 160kb MP3's being played by the built-in media player report:

1. Clock = 125mhz, 500mhz and 800 mhz (fluctuates, but mainly on 125)
2. CPU usage does not deviate from 50% to 53% (4 point range)

Usage seems to not correlate well with what the clock is reporting at the same time. Why go from 125mhz and up to 800mhz, yet usage never deviates from within four point of 50%.
